Attorney JAZZ/1100 Inventors earns TE GEORGE F. HULLINGS AND DAVID P. MOORE, OF WASHINGTON, DISTRICT OF COLUMBIA.

Application filed April 27, 1914.

To all whom it may concern:

Be it known that we, GEORGE F. HUL- LINGS and DAVID P. MOORE, citizens of the United States, residing in the city of lVashington and District of Columbia, have invented certain new and useful Improvements in Staple-Afiixing Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

Our invention relates to improvements in staple aflixing machines, one object of the present invention beingthe provisionof a peculiar anvil mounting whereby the ma chine is adapted for various kinds of work, as stapling corners of boxes, telescopic boxes, fold flap closure boxes, and papers,

there being provided means for quickly ad-' justing and locking the anvil in any selected position. y

A further object of the invention is to provide a staple affixing machine, in which the magazine and plunger are quickly detachable from the base and operating mechanism so that the same may. be readily removed and replaced when the occasion may arise.

A still further object of the invention is to provide in addition to the stapling means, perforating devices that produce perforations in the paper or box about the staple, whereby the smaller piece of material surrounded by the perforation may be removed from the box to permit access to the interior thereof without destroying the complete box.

A still further object of the present invention is to so combine a pivoted staple carrying magazine having a spring elevated plunger. and a spring elevated main operatinglever, depressible through a treadle, that when the treadle is depressed, the lever in moving downwardly will through the plunger and the resistance of the spring of the plunger depress the magazine upon the anvil, the plunger not being affected in its downward movement until the magazine is at rest.

'lVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of Specification of Letters Patent.

Patented Nov. 17, 1914. Serial No. 834,746.

the invention herein'disclosed can -be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawingsFigure 1 is a side elevation of the complete machine assembled for use. F ig. 2 is a side elevation of the operating parts of the machine on an enlarged scale. Fig. 3 is a top plan view of the anvil, and theadjacent portionof thebase. Fig. i is a bottom plan view of the anvil, the operating and pivot members being in section. Fig. 5,113 a bottom plan view of the base and anvil as viewed in Fig. 4. Fig. 6

is a section on line 66 of Fig. 3. Fi 7" 1s a top plan view of a modified form of anvil. Fig. 8 is a bottom plan view of the magazine adjacent the plunger end. Fig. 9 is a detail view of the operating rods and clamps.

Referring to the drawings, the numeral 1 designates a bracket, which is adapted to be fastened to one side or corner of a table or suitable support 2, so that the base 3 and the auxiliary base 3 of the machine is properly disposed beyond the top of the. table for ready operation upon different classes of work.

Upstanding from the base 3 at the rear end thereof is a supporting member orstandard at which has disposed in the upper end thereof, a pivoting pin 5 for the main operating lever 6. This operating lever 6 has insertible intermediate of its ends, an apertured pin 7 which has threaded through the opposite ends thereof, the two parallel operating rods 8 which extend downwardly and are projected through the clamping bar 9 and secured adjustably thereto by means of the set screws 10. A set screw 11 secures the single rod 12 in proper relation so that the foot treadle 13 will be properly elevated above the fioorfor manipulating to draw the lever 6 downwardly, as will presently appear.

Carried by the supporting member 4 and projecting forwardly therefrom, is a lug 14 provided with a spring holding pin 15 which receives the lower terminal of the coiled spring 16, while the other terminal engages the pin 17 disposed upon the under side of the main operating lever 6. This spring has a normal tcndencv to expand and therefore elevates the lever 6 to hold it in the normal position as shown in Fig. 2. Carried by the auxiliary base 3 adjacent the its rear end thereof is an apertured lug 18 which has mounted therein by means of the removable pin 19, the staple magazine 20'.

This-magazine is disposed so that its forward end is moved to and from the forward end of the auxiliary base- 3, the purpose of which will presently appear. v

. Mounted for sliding movement in the free end of the magazine 20 is a plunger 21 which is normally held elevated by-means of the coiled spring 22, a removable pin 23 being projected through the upper end thereof and the .elongated slot 24 of the main operating lever 6, so that when the lever 6. is primarily moved downwardly the spring 22 will offer jsufiicient resistance to permit the magazine 20 tov he placed so that its lower edge is in 7 parallel with the upper surface of the base 3 before the plunger 21 is depressed to sever the auxiliary base as clearly illustrated in Fig, 6 and is held'against upward displacement by means of the locking. screw 27. Projected through thearcuate slot 28 formed 'through'the base and auxiliary base with the center ofthe'pin 26 the center of the-slot, I is a screw 29 which is threaded in the anvil so that when the milled head 30 is'manip ulated,the portion 31 thereof willbe moved into and out'of engagement with'the under side of the base 3, so ast'o clamp the anvil 25 and release the same from adjusted posi- '-tion. The block '25; due to the arcuate slot 28 which is one-quarte r.of 'a circle is thus permitted amovementof 90 degr'ees,.the purpose of which will presently appear.

Sea-ted within'the upper surface of the block. 25 and removably attached thereto by means ofthe' screws 32 is ahard tempered plate 32 which is -provided with the blade anvil 33 carrying the clenchingrecess 84s'and thenarrowerblade anvil 35 which i'sT proQ vided withthe clenching. recess 36. By this means it will be seen that either one of the anvilsmay; be positioned so that its elench-.

ing recessis disposed below theplung'er 21 to receive and clench the staple which is detached and driven by the plunger.

, As clearly'illustrated in Figs'tQ, 3 and ,8,

there is formed upon and carried by the. magazine 20at the under side'thereof to the rear ofbut adjacent to the plunger 21, a plurality of perforating members 38, in this l instance shown in the form of a segment,

these being positioned to cooperate with the recesses 37 formed inthe anvil 33, so that when the magazine is positioned fdownwardly upon the anvil, aportion of-the-niaand drive a staple S from its'strip- Thusbeing especially adapted for use in connection' with articles, portions of which donot have to be punctured by the blades asheretofore described and particularly relates to securing box corners and the like.

provided with a piercing anvil 33? and a clenching recess 34* is carried-by the block 25 so that this block combines the ordinary anvil and piercing anvil in one.

, It will thus be seen that in both forms of A small blade 32 of hard tempered metal anvils, the manipulating and adjustingscrew 29- is in ready access to the operator from the front so that the parts. may be rea lily moved to present eitherone of the recesses 34, 36, 34* or 40 below andin linef with the staple severing and delivering plunger 21." By this means, this form of. machine may be adapted for various uses and by attaching the machine for operating by foot power both hands of the operator are free to position the work upon the-various anvils to receive the staples. 1

From the foregoing description, it is' evi dent that bythe peculiar mounting of the 1 lever 6 and'itsspring 16, the magazine and its spr ing elevated plunger, that upon the depression of the lever 6 and during the, de-

pression thereof, the magazine is first lowered and brought to rest'upon the anvil, the

plunger not' being depressed to drive and- Uclench th'e staple until the above is accomplished. This is. of the utmost importance sharpblow is necessary to properly drive, v

ina machine of this character in that, a

and clench the staple and the anvil and magazine must be in the closest proximity "to each other at-this time.
